Calcium carbonate is a chemical compound found in nature and used in agriculture as a soil pH neutralizing agent. Soil pH is a measure of the acidity or alkalinity of the soil and is an important property that affects plant growth and health.

In the specific case of growing tomato plants, calcium carbonate is an important agricultural input as it helps correct soil acidity and promotes an optimal pH for plant growth. Most tomato plants grow best in a pH range between 6.0 and 7.0. If soil pH is too acidic (below 6.0), tomato plants may experience deficiencies in nutrients such as calcium and magnesium, and plant growth and yield may be affected.

Regarding the granulometry of calcium carbonate, the choice of the appropriate particle size can affect the speed and effectiveness of the chemical reaction in the soil. In general, it is recommended to use calcium carbonate with a fine granulometry for a better effect on the pH of the soil, since the fine particles dissolve faster and are distributed more uniformly in the soil, the granulometry 150 microns (0- 0.15 mm) is perfect.

Regarding the dosage of calcium carbonate for growing tomato plants, the amount and frequency of application will depend on factors such as the acidity of the soil, the texture of the soil, the variety of tomato plant, the growth stage of the plants and the quality of irrigation water. In general, it is recommended to perform regular soil tests to determine the proper dosage of calcium carbonate and adjust the dosage as necessary.

It is important to keep in mind that calcium carbonate is a complementary agricultural input and should not be used as a sole solution to correct soil pH problems. Other factors such as fertilization, irrigation and crop rotation are also important to maintain healthy and productive soil.
